If it is Real, What Game Would it be the First?

Would Sony Say Yes?
Most likely yes. Sony has no problems with Microsoft unlike like whole Sony and Nintendo drama. However there is chance that Sony might say NO. As you may know, recently Microsoft did a crossover with the Switch recently. Because of that the Sony might say no, but that's kind of childish. However, there is a bigger possibility that Sony will say yes, just because of the fans out there. For many years the fans has been asking for it. It will probably become reality. Even if they say no, people will probably hate them afterwards.
How That Would Change Everything
Sure I admit, it wouldn't change EVERYTHING, but it will change quite a stuff in video game history. Firstly, this means that there can be more crossovers between the consoles, which can lead to more fun games which you can play with your friends even if you guys have different consoles.
Also, this would mean there could be more consoles coming out that can do crossovers! I mean think about doing Rocket League with a Xbox player or a PS4 player. That's going to be cool!
